Stepping off a plane and into the new Calgary International Airport (YYC) is a transformative experience. Natural materials, including wood, metal and stone channel the essence of the surrounding region, while expansive windows show off views of the Canadian Rocky Mountains. Designers from around Canada worked for several years to cultivate a design that blended aesthetic beauty with functionality and sustainability.

Late in 2016, the Gypsum Association (GA) released five revised technical documents. GA-220-2016 Gypsum Board Winter Related Installation Recommendations; GA-223-2016 Gypsum Panel Products, Types, Uses, and Standards; GA-226-2016 Application of Gypsum Board to Form Curved Surface; GA-234-2016 Control Joints for Fire Resistance Rated Systems, and GA-338-2016 Guidelines for Prevention of Mold Growth on Gypsum Board have been updated to reflect current best practices. As a service to the design and construction community, these documents, and more than thirty additional technical documents, are available for free download through the GA Bookstore.
